line a set of connected points that extend forever in two directions
Collinear points that lie on the same line
Ray a portion of a line that has a starting point and then extends forever in one direction
Segment a portion of a line that has both a starting point and ending point
Angle two rays that share the same starting point
Acute angle an angle measuring less than 90 degrees
Right angle an angle measuring exactly 90 degrees
Obtuse angle an angle measuring between 91 and 179 degrees
Straight angle an angle measuring exactly 180 degrees
Adjacent angles two non-overlapping angles that share a ray
Vertical angle pairs pairs of angles that share a vertex point and have rays that point in the opposite directions
Complementary angle pairs two angles whose measures add up to 90 degrees
Supplementary angle pairs two angles whose measures add up to 180 degrees
Midpoint a unique point that lies at the center or middle of a line segment
Bisector cuts a geometric object into two of the same type of objects with the same measure
Segment bisector cuts a line segment into two equal line segments
Angle bisector cuts an angle into two equal angles
Perpendicular two lines, segments, or rays that form right angles with one another
Parallel two lines, segments, or rays that share no points in common; they will never intersect and the distance between them never changes
Transversal a line that intersects two parallel lines; there will only be two angle measures for the eight angles created
Interior Angles the inside four angles formed when a transversal line crosses two parallel lines
Exterior Angles the outside four angles formed when a transversal line crosses two parallel lines
Corresponding Angles angles located in the same relative position on the two parallel lines

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
